System Information

System Description

A low channel dam along the Vermilion River (Illinois) stores 1075 ac-ft of water and an additional 728 ac-ft can be pumped into an old quarry, which functions as an off-channel reservoir, a storage basin for low nitrate water, and a pre-treatment sedimentation basin. Water can be pumped from the river to the treatment plant using three 2 mgd pumps and from the river to the off-channel reservoir using one 5 mgd pump.

1989 Study:

50-year drought yield sufficient at present level of water use.

USGS Gages:

Vermilion River near Leonore (05555300)

Developments since 1989:

Streator has installed a small ion exchange plant because storage in the reservoir is insufficient for blending during extended periods of high nitrate concentrations in the Vermilion River.

Note: *A low channel dam on the river creates storage as noted in the table.
